Wow! You haven't posted in over 5 years. This was worth the wait.

" I had the BBS running on that within a few hours." Is this because the 6502 opcodes are a subset of the 6510 ? Did anyone encourage and assist your curiosity or was it just you and an advanced Commodore technical/reference manual ?

Related I did C64 computer repair in high-school and also lived in NYC. I sold modified peripherals to work with Commodore's Amiga, or game accessories like a parallel port attachment to allow 4 joysticks on games (e.g., Gauntlet). I shipped COD (cash on delivery) and advertised for free on BBS's. It was exciting and I was able to eventually qualify for in-state tuition at ASU partly from the money I had earned over those years ensuring I could afford to graduate.

Re:MIT professor says AI is taking over your brain on Thursday October 29, 2026 @12:45PM (#50292005)
My father encouraged me to avoid elevators and escalators to the extent possible. He worked in a high rise and used the stairs for the first 6 floors of the building. People would see him come out of the stair well on the sixth floor to catch the elevator the rest of the way. Some coworkers eventually picked up this habit. He's 87 and is one of the healthiest people I know.

It's not just elevators and LLMs, we should regularly question all our technology usage. I needed to solve a statistical problem recently and it is easy to brute force an approximation by running a few million iterations on a computer. But I forced myself to attempt a theoretical solution first. It only took a few minutes to rejuvenate concepts and "foundational cognitive ability" that would otherwise be fading.

I looked through your comment history to ensure you haven't already answered this. But what made you get tested ? Did you have risk factors ? No problem if you'd rather not share.

Related, I was told by a doctor to get screened after turning 50. But a reasonable self-estimate given all my risk factors puts my chances of having colon cancer at 1 in 10000. A colonoscopy has a false positive of ~2%[0] for my demographic. Meaning if I get a positive result, it's actually ~200 times more likely that I don't have cancer. It's hard to justify a screening given those odds and the 99%+ chance I will waste my time treating and worrying about a disease I don't have. My guess is an insurance company wouldn't cover a colonoscopy for those reasons.

Returns are already a major expense for wholesalers and retailers. Hopefully accounts using chatbot agents will have to pay a restocking fee on returned items that is partly paid to the wholesaler.

Perhaps this post is merely for publicity's sake much like retailer's cryptocurrency support claims in 2018.

The correct term is "chatbot" in most cases. I've witnessed people make dumb decisions somewhat blindly because "AI" recommended it. If they had called it a chatbot maybe some skepticism would have kicked in.

Fun site and your Muse is a near match to Meta's.

Curious, did you come up with the name "Muse" and make the character art ? Or did you and Zuck coincidentally use similar LLM prompts. If Meta's version was AI gen'd they wouldn't be able to copyright it suggesting it's likely human designed. But if that human design is a derivative of your art, which it seems to be, then they wouldn't have copyright either.

"People who spoke two languages had brains about six... three about seven... and four roughly 13 years younger."

I am fluent in at least 10 programming languages. Do those count ? Probably, if this study revealing a hidden correlation such as socioeconomic level. But they did reference that possibility.

"The researchers adjusted their analysis for factors including age, sex and education... lifestyle and social engagement, could also contribute to the differences they observed."

"but as long as we all believe it has value, it does".

Would one argue that an airplane is a _story_ ? If no one believed in the technology and lost faith in all pilots no one would fly. But that doesn't change the reality of the technology and competence of the pilots.

I get the sentiment, but I am not sure _story_ is the right word.

Re:`Mr AI' Peter Thiel Lectures about Antichrist in Rome on Tuesday March 17, 2026 @04:13PM (#47417672)
From personal observation, many Christians see oil as a unlimited natural gift from God and view alternative energy sources with disdain. Not sure if that was a deliberate strategy on Big Oil's part but it effectively solidifies massive political support.

By similarity if Thiel can equate AI regulation or restricting government AI funding with the Antichrist he could guarantee political support for decades.

I don't recall Thiel ever lecturing about religion or the Antichrist prior to his involvement with government contracts. It's hard to believe any of this is sincere.

Re:I'm going to cure my girlfriend's brain tumor on Saturday February 07, 2026 @12:09AM (#46921503)
Agreed that initially referring to it as "brain tumor" would have been fine.

Thanks for sharing your story too, perhaps this condition isn't that rare. Coincidentally I once went into bar and vaguely recognized a roommate I hadn't seen in years. His appearance had changed and he now had remarkable Hulk like features. I restrained myself from asking but I honestly thought he looked great.

We chatted and he shared that he had "brain surgery" 2 weeks(?) prior to remove a tumor on his pituitary gland. He just woke up one day and his vision was distorted. The next day he woke up blind which lead to him getting a diagnosis and surgery. I assume he had also contracted giantism over the years prior to going blind.

If I recall, the surgery was performed going behind his nose through an incision in his mouth above the posterior of his upper lip which differs slightly from the approach in the OP. It's amazingly fortunate that this is an option given it looks inoperable from the MRI.

I'll also share that towards the end of our conversation he thanked me for not commenting on his appearance and that he was self-conscious. It's compelling, especially when someone looks good, to mention it, but there's no need to lead with it.

Re:Don Norman on how design fails older consumers on Friday May 10, 2019 @10:49PM (#19884214)
Regarding a comment the author made in passing:

For the increasing number of people who have cataract surgery, the eye’s lenses have ben replaced with plastic, which usually have a fixed focus. (Artificial lenses that can be focused are under development.)

My dad recently had cataract surgery and I just assumed he was getting would be a deformable lens that would give him the ability to focus again. Does anyone know why it is so hard to develop such a lens ? As far as medical breakthroughs it seems like low hanging fruit and most people over the age of 45 could benefit from such a surgery since that is the age at which our lenses begin to harden and can no longer be shaped by our ciliary muscles.

Re:Ask HN: Amazon delisted me – what do I do? on Tuesday April 02, 2019 @02:32PM (#19557177)
In addition to those consultants, Cynthia Stine of egrowthpartners.com was recently interviewed in The Week's Jan 25, 2019 "The Last Word" column and her firm helps Amazon Sellers with Marketplace challenges.

Also, Amazon's Selling Partner Summit is taking place next week at Amazon HQ. It is currently sold out but maybe there is a waiting list ? I'll be attending primarily to make internal contacts should I ever encounter a problem with my account but I can't say for certain if that conference will be helpful in that regard. Sorry for this situation and good luck!

Re:Why Are Human Teeth So Messed Up? (2017) on Sunday March 17, 2019 @11:13PM (#19418446)
This article implies that if you can't change your diet then you could achieve similar results with chewing exercises. The comments below mention mewing, but I suspect greater force would be better. Googling "chew toys for adults" gave interesting results but they are mainly used for anxiety and ADHD. Curious if anyone knows of a chew appliance for children or adults that would address the issues mentioned in the article.
Re:A PhD state of mind (2018) on Wednesday March 06, 2019 @08:33PM (#19324843)
A bit of a tangent, but does anyone know if a "paper PhD" is still and option ? The first and only time I ever heard of it was during a lecture by Nobel laureate Dr. Shuji Nakamura[1].

IIRC, the University of Florida offered PhD's if you published 5 papers which he did in one year.

Re:Carbon Removal Technologies on Tuesday October 23, 2018 @08:19PM (#18288636)
"It's time to invest and avidly pursue a new wave of technological solutions to this problem - including those that are risky, unproven, even unlikely to work".

I had a recent crackpot idea that falls into the "unlikely to work" category since my background is not chemistry.

Given that a modern automobile's tailpipe emissions are mostly C02 + H20, those molecules can be converted into ethylene (C2H2) using known efficient electro-catalytic processes. The conversion of ethylene gas to a polyethylene (plastic) is well known and has the added benefit of being exothermic.

The end goal is for my car to output a lump of plastic I can drop into the recycling bin instead of CO2.

But my gut tells me that:

1) There is no way to speed up the reactions to keep up with the 80 liters per second of tailpipe exhaust (~40rps * 2.0 liter engine) without this system being impractically large and/or requiring energy intensive compressors.

2) No one, including me, wants to drive around with a tank of hydrogen and a tank of ethylene gas.

But still, it might be fun to hack on something like this assuming I can do it safely. If anyone has any feedback, or has experience making polyethylene, I would be grateful for feedback even if it is negative. Thanks.

Then forget exercise for now, just take a contemplative walk around the block. Perhaps do it right before breakfast and/or after dinner. It's easy and takes less than 10 minutes. Don't think of it as exercise and do it in any clothes and with any shoes. No excuses, anyone can walk around 1 block and everyone needs 10 private minutes to collect their thoughts.

Before you know it you'll find yourself walking around several blocks, then swinging your arms, then walking faster, then you may even start jogging. You'll feel motivated, you'll keep making progress, and most importantly, you'll actually look forward to your walks.

I followed the advice above and now run almost daily before sunrise. It has really boosted my self-esteem since I had always disliked running yet admired those people who run before sunrise. But if someone had told me to start by purchasing running clothes, finding the right running shoes, choosing a good running route, stretching for 10 minutes... forget it! However, I will make one recommendation. This mask is helpful on mornings when it is below 40F. https://www.amazon.com/gp/product/B0796R1DPG . Please, start tomorrow morning and report back. :)

Re:Good sleep, good learning, good life (2012) on Wednesday October 17, 2018 @03:09PM (#18242610)
"I could get hit by a bus and die tomorrow"

Ironically, when I am sleep deprived I am more accident prone and more likely to get hit by a bus.

But what's almost certain, if I sleep less than 7 hours for more than 1 week, I will catch a cold. My immune system doesn't work as well without sufficient sleep.

How is calculation of health insurance premiums not #1 on this list ?

Recently I purchased a DIY mole removal product from Amazon. An expansive actuary table would show a "concern about moles" has a slight positive correlation with "skin cancer". Arguably my premium should go up because of this.

It also blows my mind that Amazon won't allow you to delete a purchase from your Amazon order history. It is there forever and there is no reason that data can't be sold even if the account is closed. To be fair I am making assumptions without having read the privacy policy in Amazon's EULA.

Re:Jason Fung explains why intermittent fasting diets work on Friday October 12, 2018 @04:49PM (#18204618)
I am not an expert on psychology, but your goal "losing more (fat) and gaining more(muscle) as fast as humanly possible", might be detrimental to your success.

It probably took decades to get to your current body weight. Should it not then take at least 5 years to get back to your target weight ? True the caloric math shows you could probably get to 250lbs in a year with a 600-800 a day diet. But can any human actually stick with that diet for more than a month ? If not, you would be better eating 1600-1800 a day if you could stick with it for a year.

As an aside, at times I wonder if our obesity epidemic is in part related to an ever increasing target/acceptable weight. When I was a kid, if you could pinch an inch, you were overweight (I stop drinking calories if I pass the threshold). Even my childhood bathroom scale maxed out at 250 which implied that 250 must be extreme morbid obesity.

I know this is personal, but when you were young did you ever have such thresholds (weight, mobility, etc.) in mind ? Or did it just sneak up on you and by then you were in gaining weight at a surprising rate beyond your control ? No worries if you are too busy to respond. I wish you the best!

Re:Jason Fung explains why intermittent fasting diets work on Friday October 12, 2018 @03:54PM (#18204236)
Given that poor sleep quality exacerbates insulin resistance, it is possible that by not eating late into the day, the research subjects in the article's fasting study may have also lost weight because their sleep improved.[1]

Personally if I eat dinner after 5PM, I have trouble sleeping.

Re:A RISC-V chip with built-in neural networks on Monday October 08, 2018 @09:21PM (#18172660)
If you are a hacker you probably would likely take a tech powered short-cut. Google has a translator toolkit that lets you upload documents and also create a glossary for technical terms and consistent terminology. Haven't tried it yet but it would be great to start a crowdsourced glossary for electrical engineering documents if one doesn't already exist.
